用NTLM在Ruby中给出"401未授权“的机械化

Question

我有一个用于抓取数据的脚本，但由于NTLM身份验证，我无法在一些intranet站点上正确地进行身份验证。

代码如下：

require 'mechanize'

url = 'http://intranet/somesite.asp'
agent = Mechanize.new
agent.auth(url, 'my_login', 'my_password')
agent.get(url) do |page|
  puts page.title
  puts page.body
end

这是返回的错误信息：

/home/igallina/.rvm/gems/ruby-2.2.2/gems/mechanize-2.7.3/lib/mechanize/http/agent.rb:753:in `response_authenticate': 401 => Net::HTTPUnauthorized for http://sistemasnet/srd/Consultas/ConsultaGeral/TelaListagem.asp -- NTLM authentication failed -- available realms:  (Mechanize::UnauthorizedError)
    from /home/igallina/.rvm/gems/ruby-2.2.2/gems/mechanize-2.7.3/lib/mechanize/http/agent.rb:302:in `fetch'
    from /home/igallina/.rvm/gems/ruby-2.2.2/gems/mechanize-2.7.3/lib/mechanize/http/agent.rb:788:in `response_authenticate'
    from /home/igallina/.rvm/gems/ruby-2.2.2/gems/mechanize-2.7.3/lib/mechanize/http/agent.rb:302:in `fetch'
    from /home/igallina/.rvm/gems/ruby-2.2.2/gems/mechanize-2.7.3/lib/mechanize/http/agent.rb:788:in `response_authenticate'
    from /home/igallina/.rvm/gems/ruby-2.2.2/gems/mechanize-2.7.3/lib/mechanize/http/agent.rb:302:in `fetch'
    from /home/igallina/.rvm/gems/ruby-2.2.2/gems/mechanize-2.7.3/lib/mechanize.rb:440:in `get'
    from mechanize_scrape.rb:6:in `<main>'

我已经尝试了所有三种方法，但都没有成功：

add_auth
auth
basic_auth

我还试图提供更多的参数，比如realm和domain，尽管我并不真正理解realm是什么。

刚经历了机械化问题，意识到他们放弃了对NTLM的支持。
